Abstract
Elastomeric vinyl acetate- ethylene copolymers having high Mooney viscosity and low gel content are prepared by the process which comprises: a) copolymerizing from 40% to 70% by weight of vinyl acetate with from 60% to 30% by weight of ethylene in an aqueous emulsion reaction medium to provide a latex, the reaction medium containing: (i) at least one surface active agent in an amount above 2.0% by weight of the total monomer. (ii) a polymerization catalyst, and (iii) at least one protective colloid in an amount of less than one part for each part by weight of total surface active agent, with the total weight of the surface active agent and vinyl acetate being present in the reaction medium at the commencement of copolymerization; and, b) recovering the vinyl acetate- ethylene elastomer from the latex.
